When the freewheel lock is disengaged (when either of the forward gears is engaged and clutch released beforehand) the Syncro system will act as any other ‘normal’ Golf, and can therefore be towed with front wheels lifted.

The thing is, when done in the above stated order, the rear wheels will spin freely (hence ‘free-wheel lock’) on their internal planetary differential.
This way, the only way to activate power to the rear wheels is when the front wheels start turning faster than the rear wheels do. But in the case of lifting the front and towing the vehicle, the front wheels do not turn at all, so no power is transmitted to the viscous coupling, so no power is needed to turn the rear wheels, who in turn start spinning on their planetary differential.

Only when the free-wheel lock is engaged, it will lock the crown wheel to this planetary differential and make the rear permanently connected to the front wheels.

In case of Brake testing, the Syncro only pushes the car of the brake tester when the front wheels are brake tested (front wheels start spinning faster than the rear, so viscous coupling stiffens and hereby engages the crown wheel and turning the rear wheels)
This effect is only recreated on the rear wheels when the car is placed in reverse gear, then the Vacuum actuator manually ‘locks’ the freewheel lock.

The reason VW added the Vacuum Actuator to the Syncro, is to give the car 4wd in reverse gear as well as it would do when traveling in a forward motion.

If you like I can scan the original Syncro Suplement manual where this towing procedure is also described, although i’ve only got the German version.

Good luck

Thank you very much for that, I feel a lot better.
If you get a minute I would appreciate you scanning the Syncro Supplement.

Thanks again

I posted this question on club GTI & here is one of the replies

Note from syncro manual:

Quote:
The vehicle can be towed like any two wheel drive golf

With a recovery vehicle the car can be towed with front or rear wheels suspended

If the vehicle is to be towed with the rear wheels lifted and the rear wheels cannot turn freely, one must ensure that the freewheel in the rear axle has not been locked beforehand by driving the vehicle in reverse. To unlock the freewheel the gear lever must be shifted briefly into first gear with the ignition on and then back into neutral.

This depends on whether there’s enough vacuum stored to actuate the freewheel lockout release, and therefore how recently it’s been driven. To be on the safe side after the above check, I’d jack up the rear, and with a mate’s help turn both of the rear

What do you think?

Thanks for the reply.

That’s not what I wanted to here, I had my Rallye collected and taken to a garage when I was at work and they towed it with the front wheels up on the tow truck. (my wife phoned me to let me know)

I had told them that it was four wheel drive and would need to go on a flatbed.

What damage will it have done?

How can I check when I go to collect it?

ah yes – damn sorry, completely forgot to update! Fixed it with bells on

I didn’t even need to go as far as measuring the current drain and removing fuses because I just thought I’d have a poke around and see if I could see anything. I peeked into the boot by folding the seats forward and tadaa – light was on. The switch had got knocked through the plastic so was always on.

We also installed solar chargers in both cars and they’re great! I’m thinking I’ve got space for a couple more on my parcel shelf and it might be enough to charge a separate battery (perhaps a small SLA) which would be used to power an amp or a better stereo of some kind. I never bothered fitting one because the last one I had kept leaving me with a flat battery but given how much time the car spends standing it might be a neat solution.

So thanks very much everyone that was another mystery rapidly solved

Those switch have always been a pain when you least expect it.

[mk21147]

I have had faulty boot interior light push switches be faulty on several of my golfs, might be worth checking?

[mk21147]

No Rallye owners on here had problems with there ABS & used vag com to look for faults? I just want to check the wire/plug is the right one, before I go to the garage.

[mk21147]

Sounds good, any pics?

I have received an email, very helpful gentleman.

[mk21147]

No reply yet, not looking good,

[mk21147]

Stop working again, don’t think I am going to have much luck with this.

[mk21147]

Great find, thanks for posting it up. Just need some brackets making up now so it fits the Rallye beam.

[mk21147]

I hope you don’t have as much fun as I did, good luck.

[mk21147]

More emails today!!!
